Abstract: A rotor magnetic component structure and a fan motor device thereof. The fan motor device includes a stator having a radial magnetic face and a sensor member disposed under the stator. The rotor magnetic component structure includes a main body composed of multiple N poles and multiple S poles, which are alternately arranged. A magnetic force border line is formed between each N pole and each S pole. The magnetic force border line includes a first vertical section corresponding to the radial magnetic face of the stator and an inclined section obliquely extending from a lower end of the first vertical section corresponding to the sensor member. The rotor magnetic component structure is able to reduce the vibration caused in the commutation of the magnetic poles and the sensor member can find the best commutation point.

Abstract: A stator structure includes a main body. The main body has multiple poles. The poles outward extend from the main body. Each pole has a free end. An end face of the free end of the pole has an extension section normal to the main body. The extension section has multiple protrusion blocks. Each two adjacent protrusion blocks define therebetween a recess. The stator structure is able to greatly enhance the operation efficiency of the motor and lower manufacturing cost.

Abstract: A fan hub balancing structure includes a hub main body. The hub main body has a top section, a circumferential section extending from the circumference of the top section and a lip section. The lip section is connected with the lower end of the circumferential section. The lip section has at least one residual weight section on the lip section. After the residual weight section is removed from the lip section, a balancing section is formed on the lip section. The balancing structure is able to provide a balancing effect for the hub main body and facilitate the processing of the hub main body.

Abstract: A motor waterproof structure includes a stator assembly, a casing and a cover body. The casing has a receiving space formed with an open side. A circuit board is disposed in the receiving space. The cover body is disposed on the open side of the receiving space to cover the circuit board. The motor waterproof structure serves to effectively protect the circuit board from being short-circuited and burned out in a humid environment.
